I just purchased a Nesco Digital 3-in-1 Cooker (model #PC-6-25-30TPR) in time to cook Corned Beef for St. Patty's day - yummy!

This is my first Pressure Cooker and I'm excited to try some new recipes. I really like the settings (pressure, browning, steamer, keep warm and slow cook modes) digital controls, timing features, and safety of this unit (especially with 2 toddlers roaming my little kitchen) In looking at recipes, reviews and tips on the web the biggest concern/complaint about electric cookers is that some don't reach 15PSI.

How do I know what PSI mine reaches?

My Nesco PC has a high and a low setting for pressure cooking but I cannot find any reference in the manual to what PSI those are... and I haven't gotten any response from the manufacturer.

I'm not sure that a bicycle tire valve could handle the temperature of a pressure cooker (its rubber seal), but whatever the relief valve is set for should be fairly accurate -- if you know the specs for it.
